The shaft G3 receives rotation from the sprocket chain Wheel 31, by means of the sproiket chain 102. The knife shaft 68 rotates at the same speed as the shaft 22 of the printing press cylinder 23. The printing,T press cylinder 23 and the knife blade 70 are .maintained in proper operative relation by means of the adjustably1 connected sprocket chain Wheel Upon the supporting beams 32 and 33 are fastened the journal bearings and have journaled therein the shafts 103 and 10T Which are axially in line. A wooden apron drive roller 103 is fastened to the shafts 100 and 107. A sprocket Chain Wheel 109 is fastened to the shaft 10T and Connects with a feeding device, not shown. A pulley 110 is fastened to the shaft 100. A sprocket chain Wheel 111, is fastened to the shaft 107. A sprocket chain wheel 112 is fastened to the drum shaft 50. A sprocket. chain 116 Connects the sprocket chain Wheels 111 and 112, and rotation is thereby transmitted from the drum shaft 50 to the shafts 106 and 107. i

A pair of journal brackets 122 are supported on the beams 32 antL 33 and have journaled thereon the tape Wheel shaft 123. A pulley 12e is fastened to the shaft 123 and a Cross belt 125 connects the pulleys 110 and 124;, to transmit rotation from the shaft 106 to the shaft 123; A plurality of pulleys 128 are fastened to the shaft 123.

A pair of journal brackets 130 are clamped to the inner faces of the beams 32 and 33, by means of the bolts 131, Which can engage different openings 132, 133 and 1311 in said beams, for the purpose of maintaining the apron 136 to be described at the requisite tension. A roller 135 isjournaled in the brackets 130. Anendless apron 136 is supported by the rollers 108 and 135.

A pair of adjustable journal brackets 140 are fastened to the inner faces of the supporting beams 32 and 33 by means of the bolts 144 and have journaled .therein the `shafts 1111 and 142 which are axially in line.

A pair of journal brackets 148 are fastened to the top faces of the lower ends of the beams 32and 33. A tape Wheel shaft 150 is journaled in the brackets 148. Pulleys 151 are fastened to the shaft 150, and feeding tapes 152 connect the pulleys 151 and 128. The Wooden roller 1413 bears on the lower members of the tapes 152 to locate said lower members in proper operative position relatively to the apron 136.`

To operate the propelling and smoothing device rotation is imparted to the spur gear 24, and thereby the printing press cylinder different positions.

23 is turned. The spur `rear 23 rotates with the cylinder 23 and thereby rotation is transmitted to the spur gear 30. The material, in this instance the cloth 155, is delivered from a feeding;4 device to the guide roller 01,

passes under the side roller if? and from the latter passes upon the measuriruf drum 5l and entends over the fender 73. lhe ma terial 155 nent severed by the knife blades` T0 and 72 in proper lengths, depem'ling upon the speed of the measuringl drum The severed pieces 155 of the material loo slide down the feeder T3 and drop upon the endless apron 13G and are carried to the pa'intiniir press cylinder 23. The linear speed of the apron 136 equals the circlnnferential speed of the material on the measuring drum 5l. The eut pieces of material 155" are fed be tween the top member 136 of the apron 130 and the lower members 152 of the feeding tapes 152. The members 12n and 130 form a plurality of feeding.; nozzles 152g for the eut pieces of material 155e. The angle between the members 152 and 133, as Well as the pressure between the members 152n and 152c and the material operated upon can be varied by locating the idler roller 1113 in This is accomplished by locating the brackets 110 in different positions by means of the bolts 1&1. The out pieces of material are carried to the press cylinder 23 Where their forward ends are gripped by the grippers 27', and they are next delivered to a. folding machine, not shown. In case the forwarcfl ends of the eut pieces of material 155 are turned up or wrinkled they are smoothed out by the eoaction of the member 13G of the apron 136 and the members 152u of the feeding tapes 152, by reason of the said tapes running at a speed about double the speed of the apron 136. In case the forward ends of cut pieces of material 155a operated upon, are turned down, the member 13Gfl of the apron 130 continuously running forward, causes the turned-doWn ends to be straightened out. By this means the eut pieces of material 155 are delivered to the printing press `cylinder 23 in proper form.

Various modiiications may be made in the invention Without departing from the spirit thereof and the present exemplilication is to be taken as illustrativo and not limitative thereof.
